Once Caldas vs. América de Cali - More Markets

Platform comparison

Market context

Once Caldas and América de Cali meet in Colombia Primera A, and the market’s **0% YES** crowd-implied probability is an outlier against the underlying matchup data. Their recent head-to-head record has been balanced rather than one-sided: across 2023-26 meetings the sides have split wins sparingly and drawn often, including 1-1 results in January 2026 and a cluster of low-scoring draws and narrow wins in late 2024 and 2025.[5][10][16][20] Longer-run head-to-head data also points to equilibrium, with one source showing 37 meetings since 2005 split 10 wins apiece and 17 draws, which makes a zero-priced outcome easy to dismiss only if the contract is for an unusually specific sub-market.[1][3]

For traders, the key issue is whether this “More Markets” contract depends on a line-up, scoreline, cards, corners or another ancillary stat, because those can be much more volatile than the match result itself. Cross-platform comparison matters here: football databases and H2H services imply a fairly even fixture, while a prediction-market price of 0% suggests either a stale book, a misread contract definition, or a narrow event that sportsbooks are effectively treating as a long shot. The fixture is scheduled for 5 August at 9:30 pm ET, so the most relevant catalysts are team news, official starting XIs, and any late changes to match context before kick-off; if no fresh injury or rotation reports emerge, the market will likely continue to be driven more by contract mechanics than by a clear football edge.[2][8][15]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
